Bottle Sterilizer {A BABY OF BOTTLE STERILIZER}

The present invention relates to a baby bottle sterilizer, and more particularly, to a sterilizer which can sterilize and dry a baby bottle stored in a sterilization tank inside the main body at a rapid time with ultraviolet rays and hot air, and which can be used efficiently to prevent storage contamination.

The present invention relates to a bottle sterilizer, and more particularly, to a sterilizer which can be sterilized and dried quickly with ultraviolet rays and hot air, and which can be used efficiently to prevent storage contamination.

Infants and toddlers generally have a weak immunity, so baby products such as bottles, nipples, utensils, soothers, teethers, and other toys should always be disinfected before or after use.

In particular, disinfecting baby bottles in sterilized water for a certain period of time to sterilize them after the sterilization process by air drying, but this is a safety problem that can cause burns in the water to cut off and wipe the water on the baby supplies after taking out There was a troublesome problem to give.

    In addition, in recent years, a serious problem that environmental hormones are generated from a baby bottle made of plastic during boiling water disinfection causes harm to a child's health.

Another method of disinfecting a bottle is known as a sterilizer that generates steam and sterilizes baby products by the steam. However, the steam sterilizer also has a cumbersome and inconvenient problem because it needs to replenish water to obtain steam inside the sterilizer before disinfection.

Another way to sterilize bottles is UV sterilizer. In recent years, sterilization and disinfection are mainly used for cold cathode fluorescent lamps (CCFL) ultraviolet (UV) devices, and these sterilizers are not intended to sterilize bottles but are disclosed for disinfection of household goods. The household goods are nail clippers, razors, ear masks, hair combs, etc., although the bottle is also sterilized, the structure does not have the unique structure or function to disinfect baby products, especially bottles and nipples. .

    Therefore, it can not actually be used as a sterilizer for disinfecting a baby bottle or a nipple, and it is accompanied by an uncomfortable problem even if it can be used.

In addition, when the bottles are accommodated in a certain space, the parts that do not overlap or touch each other and are not directly exposed to UV rays are not sterilized.In addition, when the bottles are wet, UV rays are blocked and perfect sterilization takes a long time. It took

Another prior art is a milk bottle sterilizer published in Korean Patent Office Registration No. 20-029330. This sterilizer is equipped with a mounting part to horizontally mount the milk bottle, and a UV sterilization lamp for sterilizing the milk bottle toward the wall to eliminate the risk of leakage of water from falling water and to feed and take out the bottle into the sterilizer. A sterilizer designed to be comfortable.

However, the UV sterilizer is configured to install the UV sterilization lamp toward the wall corresponding to the entrance of the bottle in order to increase the UV sterilization effect, but the sterilization effect of the bottle is high. There is a problem that the sterilization effect is not reflected.

In addition, the device has a short life (about 4000 ~ 5000 hours) has to be replaced frequently.

Recently, a lot of ultraviolet light emitting diodes (UV LEDs) that operate at low power and have high brightness are developed. However, since the ultraviolet light emitting diode has a point-shaped optical distribution, luminance uniformity is low, and thus, sterilization power is reduced.

    Therefore, it is necessary to develop a product capable of disinfecting and storing a bottle suitable for its use and function, thereby raising awareness of the sterilizer products that have been planned and distributed around housewives and adult life, and a new customer group. Excavation has led to the need to open new business areas for sterilizers.

The present invention was devised to solve the above problems, and an object of the present invention is to provide a bottle sterilizer which can significantly improve bottle sterilization and drying.

In addition, another object of the present invention is to solve the problem of re-contamination on the bottle storage to improve the ease of use of the parenting related bottle, and to prevent the waste of time required for child care.

     Accordingly, the present inventors have diligently researched to quantify the sterilizer of the case so that the bottle can be effectively sterilized. As a result, when the bottle storage method, the ultraviolet light source and the hot air outlet arrangement are improved, the bottle is effectively sterilized. It confirmed and completed this invention.

The baby bottle sterilizer 100 according to the present invention is a sterilization tank 30 for sterilizing the baby bottle because the most necessary part of the bottle is sterilized when the baby bottle is accommodated in the storage tray 50 of the sterilization tank. The ultraviolet sterilization unit, which is a basic unit of ultraviolet light supply surface light source, is continuously disposed at the bottom to uniformly sterilize the baby bottle. This is to store the bottle upside down in the storage tray to remove the water inside the bottle, and when the stored bottle entrance is directed toward the UV sterilization unit 20, the point light source generated from the UV sterilization unit 20 is changed to a surface light source Ultraviolet light is uniformly irradiated throughout the baby bottle and includes a sterilizer which is dried and sterilized in a short time.

In addition, it includes a bottle sterilizer to solve the problem of re-contamination on the bottle storage to improve the ease of use of the child care related bottle, and to prevent waste of unnecessary time for child care.

Accordingly, as shown in FIGS. 1, 2, and 3, the main body 10 has a rectangular shape in which the front surface is open, and the door 60 is installed on the front surface thereof so as to be openable and close the base. The part 11 is provided, and the sterilization tank 30 is provided on the base part 11.

At this time, the main body 10 is the ultraviolet sterilization unit 20 and the drying unit 40 is disposed in the base portion 11 to dissipate ultraviolet rays and hot air into the sterilization tank, the sterilization tank in the drying stroke After drying the inner bottle by hot air, it is preferable that the vapor exhaust hole 12 is formed in the upper surface to discharge the wet steam to the outside.

Of course, the ultraviolet sterilization unit 20 and the drying unit 40 is disposed on the lower part of the bottle, that is, the base portion 11, so that the ultraviolet and hot air can be easily emitted into the bottle.

* At this time, since the ultraviolet sterilization unit 20 is disposed inside the main body, when the door 60 is opened while the ultraviolet rays are generated from the ultraviolet sterilization unit 20, ultraviolet rays may leak to the outside. In order to prevent such a phenomenon, it is preferable that a door opening / closing detection sensor 64 is installed on the main body base 11 to detect whether the door is opened or closed.

Therefore, as shown in FIG. 31, when the door opening signal is transmitted from the door opening / closing detection sensor 64 to the control unit 70 while the ultraviolet light is generated from the UV sterilization unit 20, the control unit 70. ) Stops the operation of the ultraviolet sterilization unit 20 to control the generation of ultraviolet rays.

Next, the sterilization tank 30 is open on the bottom and front. The sterilization tank rear part 35 is disposed above and below the main body base part 11, and an upper surface part 36 is formed above the rear part.

In the present invention, the upper surface portion 36 may be formed in a circular shape to improve the sterilization effect of the baby bottle. That is, by forming a reflector on the surface of the circular sterilization tank can sterilize the bottle in three dimensions.

In addition, since the sterilization tank is made of stainless steel or aluminum material so that the ultraviolet rays are reflected from the ultraviolet sterilization unit, the sterilization tank is formed so as to extend the sterilization region so that the ultraviolet rays are irradiated everywhere in the sterilization tank 30. .

At this time, the upper surface portion and the rear portion is formed with a reflective portion having a reflective surface to reflect the ultraviolet rays in a regular pattern on the entire inner surface, and the steam outlet 33 for discharging water vapor is formed in the upper edge portion. The steam outlet 33 may be formed to correspond to the steam exhaust hole 12 of the main body, and at the same time, a blower (not shown) may be built therein so that water vapor may be easily discharged to the outside.

According to the present invention, since the reflecting portion of the upper portion 36 and the rear portion 35 is also made the same as the reflecting portion 62 formed on the door 60 will be described in detail in the following door reflecting portion do.

On the other hand, the left and right guide rails 34 are installed at a predetermined distance from the ultraviolet sterilization unit.

In addition, the guide rail 34 is preferably formed side by side in the direction facing the guide rail 34 so that the storage tray 50 is sliding removable.

Here, the rear part 35 shows only the guide rails on the left and right side parts thereof, but is not limited thereto. The UV sterilization unit 20 may be further installed to sterilize and dry the sterilization tank in three dimensions. .

Next, an efficient sterilization object according to the present invention is provided with a storage tray in which a bottle is stored upside down in a sterilization tank, and an ultraviolet sterilization unit which is a surface light source supply unit 22 of various shapes in which a point light source is disposed below the bottle. By the continuous arrangement, the point light source generated in the UV sterilization unit is changed into a surface light source and can be achieved by uniformly irradiating the bottle while passing through the storage tray.

Another efficient sterilization object according to the present invention can be achieved by arranging a point light source such that the surface light source basic units of various shapes are continuously arranged on a basal portion corresponding to the storage tray. Accordingly, since the point light source of the ultraviolet sterilization unit of the present invention is changed to a surface light source, uniform and rapid sterilization can be achieved.

Ultraviolet sterilization unit 20 for achieving the above object is configured to include a light source and a housing. The light source is a light emitting means for generating ultraviolet light when power is applied, and an ultraviolet LED, which is a light emitting diode for generating ultraviolet light having a point light source distribution when power is applied, is selectively employed.

In the exemplary embodiment of the present invention, although a plurality of ultraviolet LEDs are electrically mounted on the substrate, the fluorescent lamps may be employed.

As shown in FIG. 3, the UV sterilizing unit 20 according to the present invention has a substrate 23 and a plurality of point light sources 21 arranged on the substrate, and accommodates the plurality of point light sources. And a housing 22 reflecting light generated from the light sources in the bottle direction.

An ultraviolet LED may be used as the ultraviolet point light source, and any form may be used as long as the point light source is sterilizable. However, ultraviolet rays can be divided into A (300 ~ 400nm), B (230 ~ 320nm), and C (180 ~ 280nm) according to their wavelengths, and UV rays in the C (180 ~ 280nm) region have the effect of killing microorganisms. It is known and therefore the present invention includes the ultraviolet light source is irradiated with ultraviolet light having a wavelength of 180 ~ 280nm.

The ultraviolet sterilization unit 20 is disposed on the lower base portion 11 of the storage tray in the sterilization tank 30 to face the baby bottle. Alternatively, the UV sterilization unit may be disposed three-dimensionally on the lower side and left / right side of the storage tray in the sterilization tank so as to face the storage tray.

The overall arrangement of the ultraviolet sterilization unit 20 is the same as FIG. 13, 14, and 15. The ultraviolet sterilization unit 20 is disposed in the base part corresponding to the sterilization area of the sterilization tank. The base portion 11 is in the form of a rectangle having a long side 11a and a cross section 11b, as in the form of a sterilization tank. The ultraviolet sterilization unit is arranged regularly throughout the bass unit 11. The base portion 11 may be divided into various shapes including a plurality of rectangles, dry models, regular hexagons, and the like, thereby providing a virtual surface light source basic unit having various shapes. The surface light source basic unit 22 completely fills the upper portion of the base portion 11 except for a portion of the edge. The light emitting distance M1, which is the distance between adjacent cells 22, is set based on the effective light emitting distance of the ultraviolet LED, and the ultraviolet LED is arranged based on this surface light source basic unit.

Hereinafter, the reason for disposing the UV sterilization unit 20 in various forms including a rectangle, a dry model, a regular hexagon, and the like, and the effective light emitting distance of the UV LED will be described with reference to FIGS. 8 to 12.

Ultraviolet rays generated from the UV LED are irradiated with the bottle on the upper part. The intensity distribution of ultraviolet rays irradiated to the baby bottle has a Gaussian distribution as shown in FIG. 6. That is, the strongest ultraviolet light is supplied directly above the ultraviolet LED of the bottle, and the light intensity decreases as the distance increases. In the light intensity graph, the distance M1 between two points corresponding to the standard deviation is referred to as an effective light emission distance. The effective light emission distance varies according to the distance between the ultraviolet LED and the baby bottle (H1 of FIG. 9). The farther the UV LED is from the baby bottle, the greater the effective luminescence distance, but the lower the brightness. The distance between the ultraviolet LED and the baby bottle (H1 of FIG. 7) can be obtained based on the housing housing the ultraviolet LED. The effective light emission distance may vary depending on the shape of the housing itself, such as the widths Wl and Wp of the housing opening 22b and the height H of the housing.

Here, as shown in FIGS. 6 and 7, the housing 22 adjusts the width Wl and Wp of the housing opening 22b, the height H of the housing, and the distance from the baby bottle (H1 in FIG. 7). It can be formed in various shapes. In the case where the widths Wl and Wp of the openings 22b of the housing are increased, the number of ultraviolet sterilization units 20 is disposed on the base portion 11 while the light spreads widely, and the height of the housing H is increased. When forming a high, there is an effect that the light is concentrated to the bottle. It is preferable that the widths Wl and Wp and the height H of each housing opening 22b are substantially the same.

As shown in FIG. 9, when the ultraviolet LEDs having the same effective light emitting distance are constantly arranged by the effective light emitting distance, the bottle is supplied with ultraviolet light having a constant intensity regardless of the position.

8 and 9 are one-dimensional, and the ultraviolet LED is shown in FIG. 10 along with the effective light emission distance in plan view. That is, the ultraviolet rays generated from one ultraviolet LED may be represented by a circle M1 having an effective emission distance with a diameter centered on the ultraviolet LED 21a.

Considering the effective light emission distance, the ultraviolet LED is densely shown on a plane as shown in FIG. 11. The distance between the centers of adjacent circles corresponds to the effective irradiation distance M1. Each vertex of the triangle shown in FIG. 11 has an ultraviolet LED.

In the arrangement of FIG. 11, since there is an empty space between the circle and the circle, the plane is divided into a regular hexagon that can fill all planes, as shown in FIG. 12A. 12 (A) is arranged in an infinite plane, and the actual placement plane has a constant size. In order to arrange the placement plane in the surface light source basic unit 20 without space, the arrangement plane is arranged in the regular hexagonal Fig. 12 (B), but it is not limited thereto, and the plane may be divided into rectangles as in the arrangement of Fig. 13, and Fig. 14 (A), The plane may be divided into squares as shown in (B), or the plane may be divided into equilateral triangles as shown in FIG.

In addition, in the empty space 22g in which the surface light source basic unit 22 is not arranged on the edge of the arrangement plane, the surface light source basic unit 22 may not be disposed. That is, since the part where the surface light source basic unit is disposed is a sterilization area for storing the bottle, the surface light source basic unit is disposed, and the empty space 22g is an area where the bottle corresponding to the edge of the storage tray is not located.

Therefore, the distance between the adjacent adjacent centers between the respective cells 22 shown in FIGS. 12B, 13, 14, and 15 corresponds to the effective light emission distance M1. When the LEDs are positioned at the centers of the cells 22 in FIGS. 12B, 13, 14, and 15, respectively, the bottle may be supplied with ultraviolet rays having a constant intensity regardless of the positions. If the LED generates ultraviolet light, the bottle is supplied with uniform ultraviolet light. If the LED emits white light, the bottle is supplied with uniform white light.

12 (B), 13, 14, and 15, the basic unit 20 of the surface light source without space in the layout plane in a rectangular, square, regular hexagon, and equilateral triangle shape capable of filling all planes Although it is preferable to arrange | position, it may arrange | position in circular and elliptical shape like FIG.16 (A), (B).

Here, the LED located in each cell 22 may not be in the center of each cell 22. However, since the distance of the LED must correspond to the effective emission distance, the LED must be regularly arranged with a distance between adjacent LEDs. In addition, an ultraviolet LED and a white light LED may be disposed in each cell to supply light. Each LED should be arranged regularly.

12 (B), 13, 14, and 15 have a long side of 11a in length and a short side of 11b in a rectangular shape corresponding to the base portion 11. The planar light source basic unit 22 is divided into an inner cell 22e that does not span a side, a cell 22c that spans a long side, a cell 22d that spans a short side, and a cell 22f that spans a corner by an arrangement plane. Divided.

In addition, the LED package 21 is located in each cell 22. The distance between the two centers facing the cell is the cell distance M1 and corresponds to the effective light emission distance. The effective light emitting distance and the cell length of the LED may be slightly different. For example, the cell distance M1 may be between 80 and 120% of the effective light emitting distance. The LED package 21 is composed of an ultraviolet LED (21a) for generating one ultraviolet light each, and a white light LED (21b) for generating white light. The white light LED 21b is configured to serve to illuminate the inside of the sterilization tank 30 when the door 60 is open when the infant wakes up at night, thereby improving product use efficiency and stopping driving when the door is closed. To control. It is preferable that the effective light emission distance of each LED is substantially the same.

According to the above embodiment, the LED package 21 is arranged regularly. Therefore, the LED package may be arranged on the substrate at regular intervals, that is, at intervals as large as the cell distance M1. The housing 22 is also arranged regularly.

Accordingly, according to the product application, the ultraviolet LED 21a, the white light LED 21b, the blue light LED 21c, and the like may be arranged on the substrate as shown in FIG. 16 (b). 21a), the white light LEDs 21c may be arranged on the substrate.

Meanwhile, as shown in FIGS. 17A and 17B, the housing is provided on a substrate 23 on which the LED package 21 is mounted. A reflector 26 having an opening 22b, each having a microreflective surface 26a on which a light reflection film for reflecting a desired light form or shape is formed, and a receiving opening 22a formed after the reflecting portion, It is formed in the shape which becomes large toward this opening part 22b. The LED package 21 may be located in each accommodation port, and the accommodation port 22a may be formed somewhat larger than the LED package.

The LED package 21 is located higher than the receiving port (22a).

The edge portion 54 may be formed at a predetermined height, and may have a rectangular shape having a long side and a cross section with an open upper surface. The edge portion 54 formed as described above forms the side wall of the storage tray 50. Accordingly, the edge portion 54 functions to prevent the cutlery from falling out. In addition, the edge portion may be provided with a plurality of air grooves for smooth air blowing.

According to the present invention, a bottom portion 53 is formed in the storage tray 50. In detail, the bottom portion 53 is integrally formed with the edge portion 54, and the support frame 51 and the connection frame 51a adjacent to the plurality of support holes 51 adjacent to the support hole 51, which is a basic unit constituting the bottom portion, are provided. It can be configured to be connected to each other.

The support holes 51 have a rectangular shape having long sides and short sides, such as the shape of the edge portion 54, and are arranged over the entire inside of the edge portion corresponding to the storage area, and are separately supported by the support holes 51. Since the member 55 is detachably coupled to each other, the bottles of various sizes accommodated in the storage tray 50 may be accommodated to be in point contact, and a variety of storage spaces may be formed. This will be described below with reference to the drawings.

20 (A) (B) is a view for explaining the arrangement of the support holes constituting the bottom portion according to the present invention, Figure 20 (C) is a view showing a support hole that is a basic unit constituting the bottom portion according to the present invention 20 (D) is a cross-sectional view showing a support hole as a basic unit constituting the bottom portion according to the present invention.

(Example 1)

FIG. 21 is a schematic perspective view of a supporting member according to Embodiment 1 of the present invention, and FIG. 22 is a cross-sectional view taken along line AA ′ of FIG. 21.

    As shown in FIGS. 21 and 22, the support member 55 may include a diffuse reflection part 56, a support part 57, and a detachable part 58.

The support member 55 according to an embodiment of the present invention is a translucent or opaque structure formed by depositing a light reflecting material or a light reflecting material to reflect ultraviolet rays when power is applied.

The support portion 57 is provided with a circular steel 57a, the length of which is formed from the top to the bottom with a predetermined diameter at the center thereof, and the length formed with the circular steel from the top to the bottom of the circular steel is expanded. The data-like portion is formed in succession in multiple stages, and the support piece 57b is formed, and its end portion has a stepped portion 57d formed in a “b” shape in contact with the bottle to stably support the bottle.

The support piece 57b may be formed in the circular steel in various forms. In the embodiment shown in FIG. 21, the support piece is formed of a plate member, and its cross section has a cross “+” shape and one end of the circular steel material. It is integrally formed on the outer circumferential surface, and the space 59 is provided in the vertical direction from the detachable portion 58 to the diffuse reflection portion 56 between the support piece and the support piece.

In addition, it is preferable that a reflecting surface 57c having a high reflectance of light is formed on the entire surface of the support piece 57b.

On the other hand, the diffuse reflection portion 56 is formed in the circular steel. Preferably, the diffuse reflection part is formed at the center of the uppermost end of the round steel.

The diffuse reflector 56 has, for example, a rectangular micro reflective surface 56a having a high light reflectance on its entire surface, and the micro reflective surface corresponding to the UV sterilizing unit is inclined obliquely to face the UV sterilizing unit.

The diameter L1 of the diffuse reflection portion 56 according to the present invention has a range between 7 mm and 15 mm. In the present invention, it is preferable that the diameter L1 of the diffuse reflection portion has a diameter of 10 mm.

When the diameter L1 of the diffuse reflection portion 56 according to the present invention is smaller than 7 mm, the reflectance of the ultraviolet rays is reduced. For example, when the diameter L1 of the diffuse reflection portion is smaller than 7 mm, some of the ultraviolet rays generated in the LED package are reflected on the reflective surface of the small area of the diffuse reflection portion, and as a result, the light reflectance is reduced.

On the other hand, when the diameter L1 of the diffuse reflection portion is larger than 15mm, the diameter L1 of the diffuse reflection portion is larger than the outer diameter of the support piece 57b of the support member 55, so that it is difficult to mount the bottle backwards. Therefore, by forming the diffuse reflector to a suitable size, the ultraviolet rays generated in the LED package is effective to sterilize the portion where the ultraviolet rays are not directly irradiated after being reflected on the reflecting surface of the diffuse reflector 56.

The diffusion reflecting portion 56 has a circular shape, for example, when viewed in a plan view. Alternatively, the diffuse reflection unit according to the present invention may have various shapes such as triangles and polygons.

Ultraviolet rays incident to the lens unit and the storage tray are incident in a range of ± 90 degrees around an optical axis extending vertically from the center of the ultraviolet sterilization unit, and ultraviolet rays having an intensity corresponding to half of the maximum intensity of light are emitted. The azimuth angle is called half-angle, and the half-angle of the LED is about 45 degrees.

As such, when the support member 55 is coupled to the support hole 51 and the bottle is stably mounted upside down on the support piece formed in multiple stages, the ultraviolet light is generated in the UV sterilization unit. It enters into a baby bottle through the lens part 25 and the storage tray 50.

Here, the lens portion 25 is preferably provided with a diffusion lens for diffusing the ultraviolet rays emitted to the sterilization tank in various directions, or by stacking the diffusion sheet to spread the ultraviolet rays in various directions.

The supporting member 55 having the diffusion reflecting portion and the supporting piece having such a configuration emits ultraviolet rays in the direction of arrow A shown by a solid line, and is shown in the direction of arrow A1 of FIG. 29. Ultraviolet ray A1 vertically incident upwardly passes through the diffusion lens 25 and passes through and guides the space 59 formed in the cross section “+” of the support member 55. While being incident inside the baby bottle is directly irradiated or reflected by the diffuse reflector (56).

In addition, as shown in the direction of the arrow A2 of FIG. 29, the ultraviolet ray A2 which is inclined upwardly with respect to the optical axis of the ultraviolet sterilization unit is reflected on the microreflective surface 26a formed in the housing 22 and is diffused. The ultraviolet ray A3 is refracted through the lens portion 25 to be inclined to the inside and outside of the bottle or reflected to the diffuse reflection portion, and as shown in the direction of the arrow A3, the ultraviolet ray A3 that is inclined upwardly about the optical axis of the ultraviolet sterilization unit is It is refracted through the diffusion lens portion 25 and inclined to enter the inside and outside of the other bottle or reflected by the support piece 57b of the other support member and diffused into the sterilization tank as a whole, and is again incident to the bottle.

Subsequently, the ultraviolet rays emitted in the directions of arrows A1, A2, and A3 are reflected on the reflecting surface of the diffuse reflector 56 or the support piece 57b, and are indirectly irradiated in various directions in which ultraviolet rays inside the bottle are not directly irradiated. Diffusion and reflection are greatly increased to improve sterilization efficiency.

On the other hand, in order to allow the support member 55 to be detached or inserted into the support hole 51, the detachable portion 58 is formed at the shortest end of the support member. In the drawing, the detachable portion has a support piece formed on the support member to be reduced in length, and its overall outer diameter is formed to be smaller than the inner diameter of the support hole. Therefore, the support part is detachably attached to the support hole 51 by the structure in which the support piece is integrally formed on the outer circumferential surface of the circular steel 57a.

Accordingly, the support member 55 requires a slight force due to the interference fit type when the support member 51 is coupled to or detached from the support hole 51.

Is formed. Accordingly, the hollow portion 59 is formed to extend in the vertical direction from the detachable portion 58 to the second diffusion lens portion 56d.

The support member 55 includes a first diffusion lens 56c which serves to diffuse ultraviolet rays generated from the UV sterilization unit 20 in various directions inside the support member in the hollow portion 59 of the detachable portion. The second diffusion lens 56d serves to diffuse ultraviolet rays incident from the first diffusion lens to the outermost portion of the support member in various directions. In addition, a diffusion pattern portion 56e is formed at the stepped portion 57d to diffuse light incident from the first diffusion lens portion 56c in various directions outside the support member.

Thus, the support member diffuses the ultraviolet rays out of the support member.

The stepped portion (57d) is formed in a "b" shape so that the end is in contact with the bottle is stable to support the bottle is provided in a plurality of support portion (57).

On the other hand, when power is applied to the ultraviolet sterilization unit and the ultraviolet sterilization unit emits light, the generated ultraviolet rays are incident on the storage tray 50 via the lens unit 25 disposed between the ultraviolet sterilization unit and the storage tray.

Here, the lens portion 25 is provided with a prism lens that serves to refract the ultraviolet rays diffused to the sterilization tank side into the effective irradiation distance of the upper surface, or laminated to the prism sheet to improve the UV intensity. It is preferable.

It is spread and irradiated in various directions inside the bottle through the lens part.

In addition, as shown in the direction of the arrow A2, the ultraviolet ray A2, which is incident obliquely upwardly about the optical axis of the ultraviolet sterilization unit, is reflected by the microreflection surface 26a formed on the housing 22, and thus the prism lens portion ( 25) is refracted and exits vertically and enters the bottle or enters the support member hollow portion, and is diffused and irradiated in various directions inside the bottle through the first and second diffusion lens portions, as shown in the direction of arrow A3, UV sterilization. Ultraviolet ray A3, which is incident obliquely upwardly around the optical axis of the unit, is refracted through the diffusion lens portion 25 and exits to the sterilization tank 30 vertically, is reflected on the sterilization tank reflector and irradiated outside the bottle again. do.

Subsequently, some of the ultraviolet rays supplied to the storage tray are emitted while passing through the storage tray, and the other portion of the ultraviolet rays is provided by the first diffusion lens 56a provided in the hollow part 59 of the support member 55.

The diffusion pattern portion 57c diffuses and emits light in various directions outside the support member 55.

In addition, some of the ultraviolet light passing through the storage tray through the lens part is reflected by the reflector of the sterilization tank 30 and is irradiated with the baby bottle.

In this case, by more efficiently and uniformly transmitting the ultraviolet light supplied from the ultraviolet sterilization unit to the baby bottle, it is possible to effectively sterilize not only the outside of the baby bottle but also the part not directly irradiated with the ultraviolet light.

Meanwhile, in order to allow the support member 55 to be detached or inserted into the support hole 51, a detachable part 58 is formed at the shortest end of the lower part of the support. As shown in FIG. 26, the detachable part is formed to be reduced in length by the support part, and the overall outer diameter thereof is formed to be somewhat smaller than the inner diameter of the support hole 51, and the outer circumferential surface thereof is perpendicular to the support hole for easy detachment. The projection 58a is formed. Therefore, the detachable portion 58 can be detachably attached to the support hole 51.

Here, the user puts the storage tray 50, the bottle is stored in the guide rail 34 in the state that the door is opened, the ultraviolet rays irradiated from the ultraviolet sterilization unit in the sterilization administration passes through the storage tray for more efficient sterilization It is preferable to store the bottle in a state that is mounted upside down on the support member (55).

Thereafter, the door 60 is closed to the main body 10, and the sterilization is performed according to a pre-input process or adjusting each detailed item of a drying stroke and a sterilization stroke through the operation unit.

Specifically, the control unit 70 operates the heater 43 and the blower fan 41 to directly supply hot air to the baby bottle through the hot air discharge outlet 46, and then blows hot air into and out of the baby bottle while the steam sterilizes the sterilization tank. The drying stroke is made while exiting through the steam exhaust hole 33 in the upper surface portion.

Then, when the drying stroke is completed, the control unit 70 operates the ultraviolet sterilization unit to uniformly generate ultraviolet rays into the sterilization tank 30 to perform the sterilization stroke.

In the second step (B3), the sterilization administration is performed while the ultraviolet rays are uniformly irradiated into the bottle and the sterilization tank for a predetermined time in consideration of the wind speed inside the sterilization tank before / after the drying stroke is completed in the first step.

Here, as the blower fan 41 is operated during a drying stroke, air flows inside the sterilization tank 30. Usually, ultraviolet rays have a constant air wind velocity value (for example, 2m / If it is more than sec), the sterilization effect is inferior, so that the ultraviolet ray may not be irradiated while the drying process is continued. Of course, ultraviolet rays may be irradiated over part or all of the drying stroke in order to reduce the operating time. Therefore, it may include an additional step of determining whether to irradiate ultraviolet rays in accordance with the wind speed in the sterilization tank (30).

On the other hand, if the door 60 is detected to be opened by the door opening and closing detection sensor 64 while the sterilization administration is in progress as described above, the control unit is the ultraviolet sterilization unit ( 20) stops the generation of ultraviolet rays to prevent exposure to ultraviolet rays.

In the third step (B4, B5, B6), after the sterilization administration is completed in the second step, if the bottle is not withdrawn, the ultraviolet rays are periodically stored at predetermined time intervals.

At this time, after all drying and sterilization strokes are completed by the control unit, it is determined whether the bottle is withdrawn through the door opening / closing sensor 64, but the bottle is not left unchanged even after the set time has elapsed. Periodically irradiate with UV setting time interval to sterilize.
